Hey everyone. My first day in. Just joined. Can anyone help regarding my Little Mark Bass II head. Completely stopped working twice at two concerts. Lost money. I'm not a gear head. No one in my city wants to touch it with a ten foot pole to repair. One repair guy who's been repairing amps for 30 + years says lighter is not better. He said Ampeg is the way to go even though it is heavier. Is there a number to Mark Bass to speak to someone live for tech support. Sorry for the long question. I'm a little desperate. My only gear. Peace.
